[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[Alexandros Kontogiannis]

Playing with different resolutions and rates using xrandr solved the
problem for me on a DELL XPS 15 with Ubuntu 18.04. If I go with a
resolution of 1920x1080 and a rate of 60 Hz the TV shows a black screen.
Changing to other modes and rates solves the problem. For example,
typing in a terminal

xrandr --output DP-1-3 --mode 1360x768 --rate 60

made it work. If I go for a resolution of 1920x1080, I have output only
for a rate of 25 Hz. I don't know why exactly this happens. Maybe it
depends on the TV?

  Secondary monitor not connecting in 18.04 LTS

Bug description:
  I have an Acer Aspire V Nitro VN7-592G-709V with Nvidia Geforce 960M
  (nvidia driver v390) and a Benq W1070 projector.

  I have upgraded from Ubuntu 16.04 to 18.04 and my projector connects
  for a split second and then gets disconnected. In Ubuntu 16.04
  projector was working fine as a mirror display and extended desktop.
  Here's what I already tried:

  - enable the nouveau driver instead of the nvidia driver -> no result
  - enable the on-board intel board with sudo prime-select intel -> no result
  - apt purge nvidia* & reinstall nvidia driver 390 (stable) or 396 (beta) -> 
no result
  - disable nouveau driver, disable nvidia driver from the repository and 
install nvidia driver from nvidia website (both 390 and 396) -> no result
  - installed CCSM (CompizConfig Settings Manager) and disabled display 
auto-detection -> no result
  - played around with the refresh rate (some forums say that the two outputs 
have to be in sync -> no result
  - deleted the whole Ubuntu 18.04 upgrade and installed a fresh 18.04 -> still 
the same issue
  - tried to manually enable the output with xrandr --output HDMI-1-2 --mode 
1920x1920 -> nothing
  - under settings -> devices -> displays I don't see a secondary display (just 
the main one)

  I have the latest libxrandr2, 2:1.5.1-1 under Ubuntu 18.04 (updated to
  day)

  Here is the output of xrandr the very second when I connect the
  projector (then HDMI-1-2 goes disconnected and no modes are
  displayed):

Just upgraded to 18.04.03 and thought I'd check if there was any action on 
this, but alas, no change. I see you were asking for a journalctl dump. Here's

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[reinhard zufall]

I upgraded my system to the 5.0 kernel of 18.04.3 recently, but the
external monitor is still not detected and also xrandr still lists HDMI
as disconnected. I was hoping badly for an improvement, but so far it
does not seem as if someone is working on this bug.

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[Ruslan Sadikov]

I have similar problem.

Acer Aspire VN7-792G with Nvida GeForce 960M and Ubuntu 18.04.2 LTS.
Try to connect to monitor Asus vx239h.

Sometimes it turns out to connect a second screen as an extension of the
screen, for example, if you go into console mode and return. It works
for a while, when you try to enter Settings, the screen turns off.

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[Thiago de Melo]

I have similar problem.

imac 27" with Ubuntu 18.04 LTS, 4.18.0-25-generic
Thunderbolt display
VGA compatible controller: NVIDIA Corporation GK104M [GeForce GTX 775M Mac 
Edition] (rev a1)

Sometimes, after logging in, both screens are on.
After shutdown, the second screen sometimes is off. 
Then, I have to restart and it could or couldn't work.

Looks like random behavior.

It would be good to have the second screen on since the boot startup.

Bug description:
  I have an Acer Aspire V Nitro VN7-592G-709V with Nvidia Geforce 960M
  (nvidia driver v390) and a Benq W1070 projector.

  I have upgraded from Ubuntu 16.04 to 18.04 and my projector connects
  for a split second and then gets disconnected. In Ubuntu 16.04
  projector was working fine as a mirror display and extended desktop.
  Here's what I already tried:

  - enable the nouveau driver instead of the nvidia driver -> no result
  - enable the on-board intel board with sudo prime-select intel -> no result
  - apt purge nvidia* & reinstall nvidia driver 390 (stable) or 396 (beta) -> 
no result
  - disable nouveau driver, disable nvidia driver from the repository and 
install nvidia driver from nvidia website (both 390 and 396) -> no result
  - installed CCSM (CompizConfig Settings Manager) and disabled display 
auto-detection -> no result
  - played around with the refresh rate (some forums say that the two outputs 
have to be in sync -> no result
  - deleted the whole Ubuntu 18.04 upgrade and installed a fresh 18.04 -> still 
the same issue
  - tried to manually enable the output with xrandr --output HDMI-1-2 --mode 
1920x1920 -> nothing
  - under settings -> devices -> displays I don't see a secondary display (just 
the main one)

  I have the latest libxrandr2, 2:1.5.1-1 under Ubuntu 18.04 (updated to
  day)

  Here is the output of xrandr the very second when I connect the
  projector (then HDMI-1-2 goes disconnected and no modes are
  displayed):

[reinhard zufall]

I can confirm that the drivers don't get loaded in 18.04 even though they are 
installed. This is also what I get when running nvidia-settings from terminal. 
ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[bartje]

I got it fixed after upgrading from 18.04 to 19.04, but it was not
upgrading that solved it. The issue is still there in 19.04.

The solution for me was disabling secure boot, purging the nvidia
drivers and then reïnstalling them.

Apparently when secure boot is on, the nvidia-drivers do get installed,
(and they show as in use by the GUI provided for it in Ubuntu) but do
not get loaded. I figured this out when running nvidia-settings from
terminal. It showed an error: nvidia not loaded.


In other words, if a developer is watching this, there are two bugs:
- 'not loading of the nvidia drivers' when secure boot is on.
- The hardware drivers GUI in 'software and updates', shows the proprietary 
driver is in use, while it is not, it's only installed, but not running.

I hope this helps.

  Secondary monitor not connecting in 18.04 LTS

  I have an Acer Aspire V Nitro VN7-592G-709V with Nvidia Geforce 960M
  (nvidia driver v390) and a Benq W1070 projector.

  I have upgraded from Ubuntu 16.04 to 18.04 and my projector connects
  for a split second and then gets disconnected. In Ubuntu 16.04
  projector was working fine as a mirror display and extended desktop.
  Here's what I already tried:

  - enable the nouveau driver instead of the nvidia driver -> no result
  - enable the on-board intel board with sudo prime-select intel -> no result
  - apt purge nvidia* & reinstall nvidia driver 390 (stable) or 396 (beta) -> 
no result
  - disable nouveau driver, disable nvidia driver from the repository and 
install nvidia driver from nvidia website (both 390 and 396) -> no result
  - installed CCSM (CompizConfig Settings Manager) and disabled display 
auto-detection -> no result
  - played around with the refresh rate (some forums say that the two outputs 
have to be in sync -> no result
  - deleted the whole Ubuntu 18.04 upgrade and installed a fresh 18.04 -> still 
the same issue
  - tried to manually enable the output with xrandr --output HDMI-1-2 --mode 
1920x1920 -> nothing
  - under settings -> devices -> displays I don't see a secondary display (just 
the main one)

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[Balazs Torma]

For me, updating drivers solved the issue. I have got Intel controller:

$ lspci | grep VGA

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620
(rev 02)


This is how to update drivers:

sudo add-apt-repository ppa:oibaf/graphics-drivers

sudo apt-get install xserver-xorg-video-intel

hope this helps.

Im having a similar problem. I have a ThinkPad T520, running xfce 4.12

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[Minato Miray]

I can also confirm the problem. The Ubuntu 18.04LTS (updated everything)
does NOT sense when I disconnect the HDMI. There is no change in /sys.
This uis the mainb problem, I guess. The events does not generate screen
switching.

Very annoying when the screen locked and disconnected from external
monitor, the notebook display remaions black!

I checked the status, and it STILL shown connected but the HDMI monitor
was disconnected:


root@notebook:~# cat /sys/class/drm/card0-HDMI-A-1/status 
connected
root@notebook:~# cat /sys/class/drm/card0-HDMI-A-1/status 
connected
root@notebook:~# cat /sys/class/drm/card0-HDMI-A-1/status 



HW: Dell Lattitude 7490


Sometimes work, sometimes NOT.

It is very annoying when I work with the notebook, it's screen remains
black after I disconnect the external monitor. I created Keyboard
shortucts to force screen UP:

Bug description:
  I have an Acer Aspire V Nitro VN7-592G-709V with Nvidia Geforce 960M
  (nvidia driver v390) and a Benq W1070 projector.

  I have upgraded from Ubuntu 16.04 to 18.04 and my projector connects
  for a split second and then gets disconnected. In Ubuntu 16.04
  projector was working fine as a mirror display and extended desktop.
  Here's what I already tried:

  - enable the nouveau driver instead of the nvidia driver -> no result
  - enable the on-board intel board with sudo prime-select intel -> no result
  - apt purge nvidia* & reinstall nvidia driver 390 (stable) or 396 (beta) -> 
no result
  - disable nouveau driver, disable nvidia driver from the repository and 
install nvidia driver from nvidia website (both 390 and 396) -> no result
  - installed CCSM (CompizConfig Settings Manager) and disabled display 
auto-detection -> no result
  - played around with the refresh rate (some forums say that the two outputs 
have to be in sync -> no result
  - deleted the whole Ubuntu 18.04 upgrade and installed a fresh 18.04 -> still 
the same issue
  - tried to manually enable the output with xrandr --output HDMI-1-2 --mode 
1920x1920 -> nothing
  - under settings -> devices -> displays I don't see a secondary display (just 
the main one)

  I have the latest libxrandr2, 2:1.5.1-1 under Ubuntu 18.04 (updated to
  day)

  Here is the output of xrandr the very second when I connect the
  projector (then HDMI-1-2 goes disconnected and no modes are
  displayed):

Still happens here on a HP Pavilion. I have tried the intel onboard
video, the nvidia, with the nvidia drivers. If it's of hep the xrandr
output shows: HDMI-1 disconnected, so it is seen but not activated. When
booting in Windows all works fine...

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[Anthony Buckley]

Thought I'd add my 2 cents worth. I only just tried adding a second monitor in 
addition to my laptop a few days ago and had this problem. Tried many of the 
suggested solutions - none worked. Works OK in windows 10. Also works OK in 
16.04. Tried using a HDMI to digital adapter at the monitor - did not work. OK 
in windows 10. Alas cannot try the adapter at the computer as no digital or dvi 
plug. xrandr pretty as in others shown above - HDMI-1 disconnected.
Hopefully this will be fixed before too long.

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[Sebastien Bacher]

Could those having this issue add their journalctl log from a session
where they try to connect the other monitor? And also give details of
the video cards/drivers you use and what screen are connected and using
what ports/adaptors/etc?

Title:
  Secondary monitor not connecting in 18.04 LTS

Status in xorg-server package in Ubuntu:
  Incomplete

Bug description:
  I have an Acer Aspire V Nitro VN7-592G-709V with Nvidia Geforce 960M
  (nvidia driver v390) and a Benq W1070 projector.

  I have upgraded from Ubuntu 16.04 to 18.04 and my projector connects
  for a split second and then gets disconnected. In Ubuntu 16.04
  projector was working fine as a mirror display and extended desktop.
  Here's what I already tried:

  - enable the nouveau driver instead of the nvidia driver -> no result
  - enable the on-board intel board with sudo prime-select intel -> no result
  - apt purge nvidia* & reinstall nvidia driver 390 (stable) or 396 (beta) -> 
no result
  - disable nouveau driver, disable nvidia driver from the repository and 
install nvidia driver from nvidia website (both 390 and 396) -> no result
  - installed CCSM (CompizConfig Settings Manager) and disabled display 
auto-detection -> no result
  - played around with the refresh rate (some forums say that the two outputs 
have to be in sync -> no result
  - deleted the whole Ubuntu 18.04 upgrade and installed a fresh 18.04 -> still 
the same issue
  - tried to manually enable the output with xrandr --output HDMI-1-2 --mode 
1920x1920 -> nothing
  - under settings -> devices -> displays I don't see a secondary display (just 
the main one)

  I have the latest libxrandr2, 2:1.5.1-1 under Ubuntu 18.04 (updated to
  day)

  Here is the output of xrandr the very second when I connect the
  projector (then HDMI-1-2 goes disconnected and no modes are
  displayed):

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[olivernz]

So, seems I have figured out the issue (at least on my Lenovo T460s) and
I think it lies with the Intel chip internal GPU.

If you use display port and HDMI-->Display Port adapter it won't work.
The Intel chip doesn't seem to support two DP connections at a time. But
you can connect Dp & HDMI-->DVI at the same time (or VGA for that
matter) & Internal display. So max is 3 displays but they need to be
different techs.

I can't confirm this for other laptops without external graphics cards
since i don't have any more.

Same here. Lenovo T460s (Intel only). Cannot use HDMI to Display Port.
HDMI to VGA works though on the same port!! The below is with HDMI->VGA.
With HDMI->DP it just doesn't recognise the display.

FYI, HDMI output works when I switch to a terminal using CTRL_ALT_F3. It
seems to not work only in graphics mode.

  I have an Acer Aspire V Nitro VN7-592G-709V with Nvidia Geforce 960M

  I have upgraded from Ubuntu 16.04 to 18.04 and my projector connects

  projector was working fine as a mirror display and extended desktop.
  Here's what I already tried:

  - enable the nouveau driver instead of the nvidia driver -> no result
  - enable the on-board intel board with sudo prime-select intel -> no result
  - apt purge nvidia* & reinstall nvidia driver 390 (stable) or 396 (beta) -> 
no result
  - disable nouveau driver, disable nvidia driver from the repository and 
install nvidia driver from nvidia website (both 390 and 396) -> no result
  - installed CCSM (CompizConfig Settings Manager) and disabled display 
auto-detection -> no result
  - played around with the refresh rate (some forums say that the two outputs 
have to be in sync -> no result
  - deleted the whole Ubuntu 18.04 upgrade and installed a fresh 18.04 -> still 
the same issue

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[reinhard zufall]

I have basically the same problem. I was using 18.04LTS on a HP ZBook15
laptop and also wanted to connect an external monitor by using the HDMI
interface. I have 2 graphics cards intel(i915) + NVidia(390drivers), and
whatever I chose in prime-select/Nvidia-settings, the external monitor
did not work. 'xrandr' always listed the HDMI port as disconnected,
which was not true of course. I also tried using different HDMI cables
due to stackoverflow suggestions, but this didn't solve the issue. Then,
I updated to 18.10, which I still use now, hoping there would be an
improvement, but nothing changed. The monitor is still not working,
"xrandr" still says that the monitor is disconnected.

Would really be great if this could be solved. Hoping for the best.
Thanks!

Title:
  Secondary monitor not connecting in 18.04 LTS

Status in libxrandr package in Ubuntu:
  Confirmed

Bug description:
  I have an Acer Aspire V Nitro VN7-592G-709V with Nvidia Geforce 960M
  (nvidia driver v390) and a Benq W1070 projector.

  I have upgraded from Ubuntu 16.04 to 18.04 and my projector connects
  for a split second and then gets disconnected. In Ubuntu 16.04
  projector was working fine as a mirror display and extended desktop.
  Here's what I already tried:

  - enable the nouveau driver instead of the nvidia driver -> no result
  - enable the on-board intel board with sudo prime-select intel -> no result
  - apt purge nvidia* & reinstall nvidia driver 390 (stable) or 396 (beta) -> 
no result
  - disable nouveau driver, disable nvidia driver from the repository and 
install nvidia driver from nvidia website (both 390 and 396) -> no result
  - installed CCSM (CompizConfig Settings Manager) and disabled display 
auto-detection -> no result
  - played around with the refresh rate (some forums say that the two outputs 
have to be in sync -> no result
  - deleted the whole Ubuntu 18.04 upgrade and installed a fresh 18.04 -> still 
the same issue
  - tried to manually enable the output with xrandr --output HDMI-1-2 --mode 
1920x1920 -> nothing
  - under settings -> devices -> displays I don't see a secondary display (just 
the main one)

  I have the latest libxrandr2, 2:1.5.1-1 under Ubuntu 18.04 (updated to
  day)

  Here is the output of xrandr the very second when I connect the
  projector (then HDMI-1-2 goes disconnected and no modes are
  displayed):

PS: workaround by Mihai to mirror displays works for me too, to get
something on the external display. Same as for Mihai, the display is not
listed anywhere.

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[llb4ll]

Also affected with Asus Zenbook UX31E and Ubuntu 18.04.01.

Cannot connect external display via HDMI. Tried to add the hdmi output
manually with xrandr as well but I cannot get the external display to be
listed anywhere.

xrandr program version   1.5.0
Server reports RandR version 1.5


Looks like the Monitor gets some information about the HDMI cable being 
connected - but no display signal is received and monitor just goes to sleep.

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[Alexis Lecocq]

Same problem with ASUS S406 (no graphic card, CPU i5-8250U)

The most awkward thing is sometimes it is working, sometimes it's not. I
can't figure out why. When not working, even a restart does not re-
enable it but xrandr can enable mirroring laptop display.

Any advice?

Title:
  Secondary monitor not connecting in 18.04 LTS

Status in libxrandr package in Ubuntu:
  Confirmed

Bug description:
  I have an Acer Aspire V Nitro VN7-592G-709V with Nvidia Geforce 960M
  (nvidia driver v390) and a Benq W1070 projector.

  I have upgraded from Ubuntu 16.04 to 18.04 and my projector connects
  for a split second and then gets disconnected. In Ubuntu 16.04
  projector was working fine as a mirror display and extended desktop.
  Here's what I already tried:

  - enable the nouveau driver instead of the nvidia driver -> no result
  - enable the on-board intel board with sudo prime-select intel -> no result
  - apt purge nvidia* & reinstall nvidia driver 390 (stable) or 396 (beta) -> 
no result
  - disable nouveau driver, disable nvidia driver from the repository and 
install nvidia driver from nvidia website (both 390 and 396) -> no result
  - installed CCSM (CompizConfig Settings Manager) and disabled display 
auto-detection -> no result
  - played around with the refresh rate (some forums say that the two outputs 
have to be in sync -> no result
  - deleted the whole Ubuntu 18.04 upgrade and installed a fresh 18.04 -> still 
the same issue
  - tried to manually enable the output with xrandr --output HDMI-1-2 --mode 
1920x1920 -> nothing
  - under settings -> devices -> displays I don't see a secondary display (just 
the main one)

  I have the latest libxrandr2, 2:1.5.1-1 under Ubuntu 18.04 (updated to
  day)

  Here is the output of xrandr the very second when I connect the
  projector (then HDMI-1-2 goes disconnected and no modes are
  displayed):

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[treb0r]

I have a Dell XPS-15 9570 and I am also affected by this bug.

I am currently running 18.10.

The external monitor does not work with HDMI at all - when I plug it in
to the machine, the monitor switches to low power mode.

The same monitor is working fine over HDMI with a Dell M3800 running
16.04

Title:
  Secondary monitor not connecting in 18.04 LTS

Status in libxrandr package in Ubuntu:
  Confirmed

Bug description:
  I have an Acer Aspire V Nitro VN7-592G-709V with Nvidia Geforce 960M
  (nvidia driver v390) and a Benq W1070 projector.

  I have upgraded from Ubuntu 16.04 to 18.04 and my projector connects
  for a split second and then gets disconnected. In Ubuntu 16.04
  projector was working fine as a mirror display and extended desktop.
  Here's what I already tried:

  - enable the nouveau driver instead of the nvidia driver -> no result
  - enable the on-board intel board with sudo prime-select intel -> no result
  - apt purge nvidia* & reinstall nvidia driver 390 (stable) or 396 (beta) -> 
no result
  - disable nouveau driver, disable nvidia driver from the repository and 
install nvidia driver from nvidia website (both 390 and 396) -> no result
  - installed CCSM (CompizConfig Settings Manager) and disabled display 
auto-detection -> no result
  - played around with the refresh rate (some forums say that the two outputs 
have to be in sync -> no result
  - deleted the whole Ubuntu 18.04 upgrade and installed a fresh 18.04 -> still 
the same issue
  - tried to manually enable the output with xrandr --output HDMI-1-2 --mode 
1920x1920 -> nothing
  - under settings -> devices -> displays I don't see a secondary display (just 
the main one)

  I have the latest libxrandr2, 2:1.5.1-1 under Ubuntu 18.04 (updated to
  day)

  Here is the output of xrandr the very second when I connect the
  projector (then HDMI-1-2 goes disconnected and no modes are
  displayed):

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[Mihai Rusoaie]

Found a workaround:

xrandr --addmode HDMI-1-2 1920x1080
xrandr --output HDMI-1-2 --mode 1920x1080

This sequence of commands enables clone display. However, I still don't
see anywhere in Displays/Monitors the secondary display.

Here is the xrandr output (while projector is on):

HDMI-1-1 disconnected 1920x1080+0+0 (normal left inverted right x axis 
y axis) 0mm x 0mm
   1920x1080 60.02*

[Desktop-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS

[Mihai Rusoaie]

** Description changed:

  I have an Acer Aspire V Nitro VN7-592G-709V with Nvidia Geforce 960M
  (nvidia driver v390) and a Benq W1070 projector.
  
  I have upgraded from Ubuntu 16.04 to 18.04 and my projector connects for
  a split second and then gets disconnected. In Ubuntu 16.04 projector was
  working fine as a mirror display and extended desktop. Here's what I
  already tried:
  
  - enable the nouveau driver instead of the nvidia driver -> no result
  - enable the on-board intel board with sudo prime-select intel -> no result
  - apt purge nvidia* & reinstall nvidia driver 390 (stable) or 396 (beta) -> 
no result
  - disable nouveau driver, disable nvidia driver from the repository and 
install nvidia driver from nvidia website (both 390 and 396) -> no result
  - installed CCSM (CompizConfig Settings Manager) and disabled display 
auto-detection -> no result
  - played around with the refresh rate (some forums say that the two outputs 
have to be in sync -> no result
  - deleted the whole Ubuntu 18.04 upgrade and installed a fresh 18.04 -> still 
the same issue
  - tried to manually enable the output with xrandr --output HDMI-1-2 --mode 
1920x1920 -> nothing
  - under settings -> devices -> displays I don't see a secondary display (just 
the main one)
  
  I have the latest libxrandr2, 2:1.5.1-1 under Ubuntu 18.04 (updated to
  day)
  
  Here is the output of xrandr the very second when I connect the
  projector (then HDMI-1-2 goes disconnected and no modes are displayed):
